ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

A damaged fuel heater caused a fuel 

leakage in the engine nacelle; investigation 

revealed that the damage to the fuel heater 

was due to chafing with an oil cooling system 

hose. 

PIAGGIO AERO INDUSTIRES (PAI) issued 

Service Bulletin (SB) 80–0175, which was 

applicable to all aeroplanes and contained 

instructions for a repetitive inspection of the 

affected parts and, if necessary, their 

replacement and/or for the repositioning of 

oil/fuel tubing if minimum clearances were 

not found. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by September 7, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2010– 

0125, dated June 23, 2010 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A damaged fuel heater caused a fuel 

leakage in the engine nacelle; investigation 

revealed that the damage to the fuel heater 

was due to chafing with an oil cooling system 

hose. 

Piaggio Aero Industries (PAI) issued 

Service Bulletin (SB) 80–0175, which was 

applicable to all aeroplanes and contained 

instructions for a repetitive inspection of the 

affected parts and, if necessary, their 

replacement and/or for the repositioning of 

oil/fuel tubing if minimum clearances were 

not found. 

ENAC of Italy issued PA 2002–335 to 

require the accomplishment of these 

corrective actions. 

WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS

43102 Federal Register / Vol. 75, No. 141 / Friday, July 23, 2010 / Proposed Rules 

Later on, PAI introduced a new Hose 

Assembly (P/N 80–337284–001), which 

allows better clearances and removes the 

problem of potential interference. PAI issued 

SB 80–0175 Revision 1, limiting the 

applicability to aeroplanes with the old P/N 

installed only and giving instructions for the 

replacement with the new Hose Assembly 

P/N. 

This new AD, which supersedes ENAC 

Italy PA 2002–335, is issued to grant the 

revised applicability and to include an 

optional terminating action, which consists 

in replacing the Hose Assembly P/N 80– 

337276–001 with the new P/N 80–337284– 

001. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

PIAGGIO AERO INDUSTRIES S.p.A. 

has issued Service Bulletin (Mandatory) 

N.: 80–0175, Rev. N. 1, dated May 14, 

2010. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 99 products of U.S. registry. 

We also estimate that it would take 

about 5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $42,075, or $425 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 32 work-hours and require parts 

costing $3,700, for a cost of $6,420 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Damages to the rudder bar locking 

adjustment tube of a non-reinforced version 

have been reported to Socie ́te ́ Nouvelle (SN) 

Centrair. This tube had been reinforced in 

1984 with a modification. Gliders produced 

before the introduction of this modification 

have not been systematically retrofitted. 

In case of rudder bar locking adjustment 

tube breaking in flight when adjusting the 

rudder pedals position, it might interfere 

with the rudder pedals which could lead to 

rudder jam or a restricted rudder movement 

and consequently, to reduced control of the 

sailplane. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by September 7, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:
